Because we do not know when we will die, we get to think of life as an inexhaustible well. And yet everything happens only a certain number of times. And a very small number really.
I think most people read and re-read the things that they have liked. That's certainly true in my case. I re-read Pound a great deal, I re-read Williams, I re-read Thomas, I re-read the people whom I cam to love when I was at what you might call a formative stage.
